The 28-year-old beauty has lavished praise on Kimberley admitting she loves and supports her friend in everything she does.
Cheryl - who flew to London from the Cannes Film Festival on Monday (21.05.12) to watch Kimberley in her final appearance in 'Shrek The Musical' - wrote on her twitter page: ''I am SO proud of @KimberleyJWalsh ... How can u love someone so much :/ (sic)''
The 'Call My Name' singer then heaped compliments onto Nicola, 26, insisting her pal has become an ''amazing young woman''.
She tweeted: ''And it is really Amazing to watch somebody grow and blossom from a teenage girl into an Amazing young woman @NicolaRoberts ... I love my Girls so much #havingamoment (sic)''
Cheryl stepped out at the UK premiere of 'What To Expect When You're Expecting' last night (22.05.12) and sent flashbulbs popping as she walked the red carpet in an off-white Victoria Beckham gown.
The star - who has a cameo in the film as a TV dance show judge - happily stopped to sign autographs for fans who had waited for hours at the BFI IMAX cinema in London to get a glimpse of the stars.
And Cheryl seemed to enjoy the event as much as her admirers, tweeting: ''Was really nice to meet/see some of you yesterday @ the What to expect when your expecting premier ! Such a Good film btw. (sic)''
